I'm in a High School, and I think this is great news. I don't teach a Saturday but not a weekend has gone by I don't think of how much it sucks that all these kids, in the prime of their lives, are being denied a something as simple as a two day weekend!
I totally agree that the parents might not share this mentality, however, it's a pretty poor show by the parents to be thinking "Ugghhh, you mean I have to look after my kid more?!". When I was living in Japan I was very aware of how the school is pretty much a second home for children where teachers take on a Quasi-counselor/parental role because parents were always so busy working and so on. But by the time children hit 13 or so, they should have the freedom to enjoy a full two days out of school. Even if they are studying, it's good for them to NOT be at school for 2 straight days. Clear the head and all that.
For the teachers too, I have never understood why ANYONE in this country would want to be a teacher. You work harder than an office worker, at High School at least and you can't get drunk as much to compensate either because you have 40 beady eyes on you the next day. Teachers must be very happy to hear the news, as long as they are not in it's abscense required to do something else. I can imagine my school, which is very academic, will fill the time with "voluntary" extra classes, that every student will attend at risk of being socially excluded.
Poor students and teachers, I feel guilty how easy (any by easy, I mean NORMAL in the rest of the world) my hours are.
